What I learned this week

This week I learned how to calculate an angle using trig functions such as sin,cos, and tan.

Latex Coding

ex 1 :

$5^2$

Example 2

$\frac{3} {4}$

Example 3

${5^2}{3^2}$ $\tan\theta=\frac{9}{12}$ $\sin 30^\circ=\frac{x}{2}$ $\cos^{-1}=(\frac{3}{4})$ $\frac{3}{4}$

I learned how to solve negative exponents by turning them into positive exponents and then solving them while using the exponent laws
